Power scaling of dispersion-managed Er-doped ultrashort pulse fiber laser with single wall carbon nanotubes.

A high-power, passively mode-locked, Er-doped fiber laser with a single wall carbon nanotube polyimide film was demonstrated in dispersion-managed dissipative-soliton mode-locking operation. The average maximum power of 285 mW and a pulse energy of 8.1 nJ are the highest values yet achieved for single-pulse operation in a nanotube fiber laser. A high-power ultrashort pulse of 680 fs was generated by dispersion compensation at a repetition rate of 34.9 MHz. Passive mode-locking was numerically analyzed, and the dynamics and output properties are discussed.
